Question

If I purchased 11 books for Rs 100 and sold 10 books for Rs 110, then the percentage of profit per book sold is?​

Answer 1

Answer:

Cost per book =10/11 and sale per book is 11/10,so % profit is =((11/10)-(10/11))*100/(10/11)=(121–100)*100*11/(10*(110))=21*100*11/1100=21%.

Step-by-step explanation:

Cost per book =10/11 and sale per book is 11/10,so % profit is =((11/10)-(10/11))*100/(10/11)=(121–100)*100*11/(10*(110))=21*100*11/1100=21%.
